Chemists and engineers have discovered a fundamental friction law that is leading to a deeper understanding of energy dissipation in friction and the design of two-dimensional materials capable of ...

Springs are a common device for storing energy. A spring which is compressed from its by an amount x from its equlibrium length exerts a force This work represents energy transferred to the spring and ...

Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, ...
